java 線程小題

public class Test extends Thread {


    public void run() {
        try{
            Thread.currentThread().sleep(3000);
        }catch(Exception e){}

        System.out.println("MyThread running");
    }

    public static void main(String[] args) {

        Test p = new Test();
        p.run();
        p.start();
        System.out.println("test");
    }
}

給出執行結果
MyThread running
test
